BTN_TOUCH is set with the first finger down, but somewhat randomly unset and
re-set when switching between the various BTN_TOOL_*TAP values.
BTN_TOOL_<N>TAP is only set for N fingers down, thus a double->triple move
will see a release for DOUBLETAP and a press for TRIPLETAP. This may happen in
the same event, or across two consecutive events.

This patch adds a fake_touches mask to the touchpad struct. The mask is set
for each matching BTN_* event and used to count the number of expected
fake touchpoints. From that we begin/end the number of actual touchpoints
